Let's solve the problem step by step using the data provided in the worksheet.
---
Given Data:
| Week | Height (cm) |
|------|-------------|
| 1 | 2 |
| 2 | 5 |
| 3 | 8 |
| 4 | 11 |
| 5 | 14 |
We are to:
1. Draw a line graph using this data.
2. Answer five questions based on the data and graph.
---
Step 1: Plotting the Line Graph
On the graph:
- The x-axis represents
Weeks (1 to 5).
- The y-axis represents
Height in centimeters (0 to 16 cm).
Plot the points:
- Week 1 → 2 cm
- Week 2 → 5 cm
- Week 3 → 8 cm
- Week 4 → 11 cm
- Week 5 → 14 cm
Then connect the points with straight lines to form a line graph.
The plant grows consistently each week, so the line will be increasing steadily.

Now, answer the questions:

####
1. How tall was the plant in week 2?
From the table:
Week 2 → 5 cm
✔ Answer: 5 cm
---
####
2. How much had the plant grown from week 1 to week 2?
- Week 1 height = 2 cm
- Week 2 height = 5 cm
- Growth = 5 - 2 =
3 cm
✔ Answer: 3 cm
---
####
3. How much had the plant grown from week 2 to week 4?
- Week 2 = 5 cm
- Week 4 = 11 cm
- Growth = 11 - 5 =
6 cm
✔ Answer: 6 cm
---
####
4. How much had the plant grown from week 1 to week 5?
- Week 1 = 2 cm
- Week 5 = 14 cm
- Growth = 14 - 2 =
12 cm
✔ Answer: 12 cm
---
####
5. On week 6, do you think the plant would be around 21 cm or 17 cm?
Let’s look at the pattern of growth:
- Week 1 → 2 cm
- Week 2 → 5 cm (
+3)
- Week 3 → 8 cm (
+3)
- Week 4 → 11 cm (
+3)
- Week 5 → 14 cm (
+3)
👉 The plant grows
3 cm per week.
So, from Week 5 to Week 6:
14 cm + 3 cm =
17 cm
Therefore, it would be
17 cm in Week 6.
✔ Answer: 17 cm
---
✔ Final Answers:
1. 5 cm
2. 3 cm
3. 6 cm
4. 12 cm
5. 17 cm
---
🔍 Explanation:
The plant shows
consistent linear growth of 3 cm per week. This makes predicting future heights straightforward by adding 3 cm to the previous week’s height.
Thus, the best estimate for Week 6 is
17 cm, not 21 cm (which would imply a faster growth rate).
